SHIFTING FOR HAMMOCK-SUPPORTS.

srncrr-rcn'rron forming part 0; Letters Patent No. 316,513, dated April 28. 1885.

(No model.)

To all whom it may concern.-

Be it known that I, CHARLES W. AGKER, a citizen of the United States, residing at Watertown, in the county of Jefferson and State of New York, have invented a new and useful Shifting Top for Hammock-Supports, of which the following is a specification, ref erence being had to the accompanying drawings. t This invention relates to tops or canopies for hammock-supports, or for lawn or field amusements; and its object is to provide a canopy or top that possesses superior advantages in point of simplicity, inexpensiveness, durability, and general efficiency, whereby it can be readily adjusted in position, and its position can be shifted as desired.

In the drawings, Figure l is a perspective view of the frame of my improved top set in position, with the awning or cover removed. Fig. 2 is a vertical transverse 'sectional view of the same, showing its adjustment in dotted lines. Fig. 3 is a vertical longitudinal sectional view thereof.

Referring to the drawings, A A designate two base pieces or strips, which are adapted to rest upon the ground, and from which the upright end posts or standards, B B, project, these posts being preferably separably connected to the base-strips by having their lower ends provided with a pin, 0, that enters a corresponding hole or recess, D, in the bottom of a recess or mortise, E, in the basestrip. At their tops the posts 13 B are provided with openings F, that receive the corresponding ends, G G, of thelongitud inal top bar,

H, which latter is rectangular in cross-section, and has its ends retained in the posts by crosspins I, inserted through perforations J.

K designates the top frame, which comprises a longitudinal bar, L, to the ends of which are pivoted divergent side bars, M M, that are connected at their outer ends by longitudinal side bars, N N. The mechanism for shifting this top frame consists of two end pieces, 0 O, that are provided with a corresponding opening, P, to receive the bar H, on which they are adapted to slide to adjust the top frame longitudinally, a connectingbar, Q, being pivoted to the top of each of these pieces 0 O, and also pivoted at the end of the top bar, L, while divergent braces R R are pivoted to the lower ends of pieces 0 O, and have their outer ends pivoted to the side bars, M M.

The main supporting-frame is adapted to support a hammock or to be placed over any lawn or field game or apparatus, and the top shifting frame,K,is covered by canvas or oth er suitable shade material, S.

The operation and advantages of my invention will be readily understood. It is very simple and convenient, and by means of the pivotal connections with the pieces 0 O the top frame can be set in any desired position at varying angles of inclination, as shown in dotted lines, Fig. 2. To effect this adjustment it is only necessary to draw the top frame over and down at either side, when the pivotal connection of the top frame with end pieces, 0 O, which is formed by connectingbars Q Q, will be correspondinglyshifted, and the connecting-braces R R will serve to retain the said top frame in its adjusted position against accidental displacement. When not in use, the top can be folded down as desired by withdrawing the pivot-bolt a, so as to de tach the pieces 0 0 from the braces R, and then folding the side bars, M, longitudinal bars N, and braces B together into the position indicated by the dotted lines marked Z, Fig. 2.

I claim as my invention- 1. Theherein-described shifting frame comprising stationary end pieces, 0, connectingbars Q, pivoted to the top of said end pieces, side bars, M, pivoted to the top of said con necting} bars Q and extending divergently therefrom, longitudinal bars N, connecting the side bars, M, braces pivoted to the bottom of stationary pieces 0 and extending divergently to the side bars, M, to which they are "pivoted, and the devices for supporting the same, substantially as set forth.

2. The combination, with the supportingframe having the top bar, H, of the top frame, comprising the longitudinal top bar, diverg out side bars pivoted thereto, longitudinal bars N, connecting the side bars, the stationary pieces supported on the top bar of the main frame, connecting-bars pivoted to '.the own-I havehereto affixed my signature in tops of said'pieces and to the adjoiriing ends presence of two witnesses; of the side bars, and divergent braces pivoted to the bottom of said pieces and to the side CHARLES AGKER' 5 bars, substantially as and for the purpose WVitnesses:

set forth. O. W. DASHIELL w In testimoiiy'thatIclaimtheforegoingasmy' 'EDW. G. SIGGERS.
